    摘要: Instructions of a program are stored at addresses sequentially designated in accordance with an M series pseudo-random number sequence in an instruction memory in the order of program addresses. A pseudo-random number program counter has a feedback shift register for generating the same M series pseudo-random number sequence and applies an address of an instruction to be read from the instruction memory to the instruction memory based on a generated pseudo-random number, and a jump address and a select signal from an instruction decoder. As a result, instructions are read from the instruction memory and executed in the order of program addresses. The feedback shift register can be implemented as a small-scale circuit and operable at high speed.

    摘要: When the CPU writes data into a memory, a 0 detection circuit detects the number of bits having the value 0 from the data. When the number of bits with 0 is equal to or larger than the number of bits with 1, the data output from the CPU is provided to the memory under control of a selector. When the number of bits with 0 is fewer than the number of bits with 1, the data output from the CPU is inverted and provided to the memory under control of the selector. Accordingly, the rewriting frequency of each memory cell from 0 to 1 or from 1 to 0 in the memory can be reduced in average. Thus the power consumption of the memory in a data writing mode can be reduced.

    摘要: To provide an image compression coding apparatus and method capable of minimizing a deterioration in picture quality which is caused on a reproduced image during an overflow of an output buffer. A picture top detector (7A) executes a picture top detection processing for discarding image compression data (S2) until a top of a picture of the image compression data (S2) is detected during detection of a start address, and restarts a normal operation after detecting the top of the picture. A processor (5) brings a detection start register (8) into a set state and causes the picture top detector (7A) to execute the picture top detection processing during an overflow of an output buffer (3a), and executes an interruption processing of rewriting, as a value of a write address register (9), an address where a top of an overflow picture to be a picture causing the overflow is stored.

    摘要: The data multiplexing device includes a header information memory storing header information, ES buffers holding encoded data of a plurality of media, an output buffer holding packetized data, and a transfer controlling unit controlling a transfer of the header information stored in the header information memory and the encoded data held in the ES buffers and writing into the output buffer as the packetized data. The transfer controlling unit can generate the packetized data simply by controlling the transfer of the header information stored in the header information memory and the encoded data held in the ES buffers, whereby the media multiplexing can be readily achieved.

    摘要: A semiconductor integrated circuit device includes a memory cell array for storing data to be processed, and an operational unit for effecting a predetermined operation on the data read from the memory cell array. The memory cell array has first and second regions for storing first and second data words of first and second groups. The first data words and second data words each include a plurality of data bits. The first region includes a plurality of bit arrays for storing data bits of the same digit in the first data words, and the second region includes a plurality of bit arrays for storing data bite of the same digit in the second data words. The bit arrays of the first and second groups are arranged alternately in the order of digits of the data words. The bit arrays storing the data bits of the same digit form one subarray. The data bits in one data word are stored in the same positions of the bit arrays. The operational unit includes operational circuits each corresponding to one of the subarrays. Each operational circuit effects the predetermined operation on the data read from the two bit arrays in the corresponding subarray. Each bit array has selectors responsive to external addresses to select one column from each bit array and connect this column to a corresponding operational circuit.

    摘要: A read only memory includes a memory cell provided at an intersection between a word line and a bit line, and a plurality of reference potential transmission lines each receiving a reference potential determined in accordance with an externally applied potential designating signal. The memory cell includes a transistor element having a gate coupled to a word line, a drain coupled to a bit line and a source which is coupled to one of the reference potential transmission lines or is held in an open state. Stored data in the memory cell is changed by switching the potentials of the reference potential transmission lines. This enables storing of different data bits in one memory cell.
